What's next:

Dry weather will persist through the weekend and into early next week, with minimal rain expected over the next five days.

Temperatures will begin sliding back toward a typical early-fall pattern early next week as a high-pressure ridge weakens on Monday and onshore flow returns. Forecast highs call for 70 degrees on Monday, with temperatures dipping into the mid-to-upper 60s under cloudier skies through the early part of next week.
